Chapter 20: Documenting the ATM Network Topology

Objectives Verify the ATM Switch Processor ILMI parameters Verify the Catalyst® ILMI parameters Enable VTP on the LANE module Discover the ATM network fabric

Objectives (cont.) Start AtmDirector™ Display the ATM network fabric Interpret the ATM topology map Display device and link information Modify the ATM topology display

AtmDirector and ILMI Uses SNMP packet types over AAL5 Adjacent nodes exchange autodiscovery information Automatically configures end-system addresses

AToM MIB Physical interface MIB Per-VCC statistics MIB ATM-layer interface MIB ATM-layer statistics Virtual channel MIB

Verifying Parameters on the LS1010 ASP Required on at least one ASP interface Used for network management

Configuring ILMI Parameters on the LS1010 ASP Enable ILMI Show ILMI status Show ILMI configuration

Configuring ILMI on the Catalyst ATM Module ILMI is enabled by default Well known VPI/VCIs are used for ILMI and signaling ILMI keepalive timers must be enabled at both ends of a link or not used at all

Enabling VTP on the Catalyst ATM Module Disabled by default Must be done before discovery Forces the default VLAN to be added Default VLAN needed for management

Configuring the LECS and LES/BUS

Configuring a Backup LECS

Discovering the ATM Network

Displaying the ATM Network Fabric

Interpreting the ATM Topology Map

Displaying Details in the ATM Topology Map

Modifying the Topology Map Preferences

Merging and Separating ATM Fabrics AtmDirector automatically merges and separates fabric maps Merges concatenate names Separation appends -1 and -2 to original names Original map must be closed to delete it
